A rare case of Dedifferentiated chondrosarcoma with osteosarcomatous and fibrosarcomatous differentiation

Dedifferentiated chondrosarcoma (DDC) accounts for approximately 10% of chondrosarcomas. It demonstrates very aggressive behaviour with a high rate of local recurrence (LR) and systemic progression resulting in a median survival of 6 months. Very limited studies have highlighted and covered the cases of Dedifferentiated chondrosarcoma with osteosarcomatous differentiation.
